Google Apps Script to protect range based on dates - google-apps-script

Question

im trying to make a google script to protect a range in google sheets based on dates
I want to protect all the rows that its date is 14 days before today
this is the code I have so far,
function ProtectEntradas() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
const sheetEntradas = ss.getSheetByName('Entradas')
var dateRange = sheetEntradas.getRange(3, 1, sheetEntradas.getLastRow() - 2, 1);
var val = dateRange.getDisplayValues();
var date = new Date();
var protectDateRaw = new Date(date.getFullYear(), date.getMonth(), date.getDate() - 14);
var protectDate = Utilities.formatDate(protectDateRaw, Session.getScriptTimeZone(), "dd-MMM-YY");
var protectRow;
//check if date is less than the current date
for (var i = 0; i < val.length; i++) {
if (val[i][0] >= protectDate) {
protectRow = i;
break;
}
}
var protection = sheetEntradas.getProtections(SpreadsheetApp.ProtectionType.RANGE);
//If protection exists, update else add new one.
if (protection.length > 0) {
var range = sheetEntradas.getRange(3, 1, protectRow, 10);
protection[0].setRange(range);
}
else {
sheetEntradas.getRange(3, 1, protectRow, 10).protect();
}
it is doing some protection, but not the range im expecting
what im I doing wrong ?
then I want to make a trigger to run every day so it will be protecting the range dinamically
Thanks in advance

Try this to compare correctly dates (3 lignes of code has been modified)
function ProtectEntradas() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
const sheetEntradas = ss.getSheetByName('Entradas')
var dateRange = sheetEntradas.getRange(3, 1, sheetEntradas.getLastRow() - 2, 1);
// #### modification on how to fetch dates
var val = dateRange.getValues().map(d => Utilities.formatDate(d[0], Session.getScriptTimeZone(), "yyyy-MM-dd"))
var date = new Date();
var protectDateRaw = new Date(date.getFullYear(), date.getMonth(), date.getDate() - 14);
// #### modification of the format
var protectDate = Utilities.formatDate(protectDateRaw, Session.getScriptTimeZone(), "yyyy-MM-dd");
var protectRow;
//check if date is less than the current date
for (var i = 0; i < val.length; i++) {
// #### modification
if (val[i] >= protectDate) {
protectRow = i;
break;
}
}
var protection = sheetEntradas.getProtections(SpreadsheetApp.ProtectionType.RANGE);
//If protection exists, update else add new one.
if (protection.length > 0) {
var range = sheetEntradas.getRange(3, 1, protectRow, 10);
protection[0].setRange(range);
}
else {
sheetEntradas.getRange(3, 1, protectRow, 10).protect();
}
}
edit : if you want to add another criterion, you will have to protect each row (or group of rows) individually
function ProtectEntradas() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
const sheetEntradas = ss.getSheetByName('Entradas')
// dates
var dateRange = sheetEntradas.getRange(3, 1, sheetEntradas.getLastRow() - 2, 1); // column A
var val = dateRange.getValues().map(d => Utilities.formatDate(d[0], Session.getScriptTimeZone(), "yyyy-MM-dd"))
var date = new Date();
var protectDateRaw = new Date(date.getFullYear(), date.getMonth(), date.getDate() - 14);
var protectDate = Utilities.formatDate(protectDateRaw, Session.getScriptTimeZone(), "yyyy-MM-dd");
// other criteria
var crit = sheetEntradas.getRange(3, 17, sheetEntradas.getLastRow() - 2, 1).getValues().flat(); // column Q
// remove protections
sheetEntradas.getProtections(SpreadsheetApp.ProtectionType.RANGE)
.forEach(protection => {
if (protection && protection.canEdit()) {
protection.remove();
}
});
for (var i = 0; i < val.length; i++) {
if (val[i] <= protectDate && crit[i] != '') {
sheetEntradas.getRange(3 + i, 1, 1, 10).protect();
}
}
}
